CALLOUS PROTECTOR.

Application filed May 16,

This invention relates to foot appliances, and more. particularly to aprotecting device forv callouses or other abnormal conditions upon thesole of a foot.

One object otthis invention is to provide a callous protector adapted tobe accurately adjusted to the size oi a `foot and to the position oit acallous upon said toot.

A further object is to provide a callous protector of this nature whichwill be simple in construction, inexpensive to manufacture, easy tomanipulate, compact, ornamental inappearance, and very efficient anddurable in use. j

Vith these and other objects in view there have been illustrated on theaccompanying drawings two forms in which the invention may beconveniently embodied in practice.

Fig. 1 represents a plan view of the first embodiment of the invention.

Fig. 2 is afsectional View ot the same, taken along the line 2-2 of Fig1,looking in the direction of the arrows.

Fig. 3 is a sectional view ot thesame, taken along the line 3--3 of Fig.1, looking in the direction of the arrows.

Fig. 4 is a side view of a human foot, showing one of the callousprotectors in opj erating position.

Fig. 5 `is a bottom plan view of amodified form of callous protectorhaving an eXtensible front strip.

Fig.v 6 is a pers ective view of 'the extensible ront strip siiown inFig. 5.

Fig. 7 is a sectional vieW taken along the line 7-7 ofFig. `5, lookingin the direction of the arrows. v

Referring now to the drawings in which like reference numerals denotecorresponding parts throughout the several views, the numeral 10indicates a callous protecting pad ot' leather, rubber, or othersuitable cushioning material adapted to be located under the sole of afoot 11 just inthe rear of the `position of a callous 12. The pad 10 ispreferably made substantially rectangular in shape 'i with flat top andbottom surfaces 13 and 14. rl'he corners 15 oit the pad 10 are curved asshown in Fig. 1, and the top ed es 16 thereof are rounded as shown inBig. 3,

whereby a smooth surface will be presented,

and all possibility of scratching or otherwise injuring the foot will beavoided.

The pad 10 is provided on its under surface with a pair of spacedsockets 16 adapted t0' be held in alinement with a pair of structed fromthin metal and havin 1927. Serial No. 191,671.

apertures 16b in a metal base `plate 17, the latter heilig permanentlysecured to the pad 10 in any suitable manner, by rivets 17a. A secondmetal plate 18 is pivotally secured to said plate 17, as by a hinge 18a,and is adapted to be detachably held in closed position parallel to saidbase plate 17 by a resilient catch member 19 formed integral with thebase late 17.

In or`er to maintain the leather pad 10 in the proper adjusted positionwithin a shoe 20, provision is made ot' an elongated relatively stitfbase strip 21 preferably concurved ends 22 and 23. The base strip 21 1sadapted to be located between the base plate 17 and the hinged plate 18,as shown in Figs. 1 and The base strip 2l has'a plurality ot' spacedapertures 24 which are adapted to be brought into alinement with thepair of sockets 16 in the pad 1() and the apertures 16", so that whenthe hinged plate 18 is moved into closed position adjacent the baseplate 17, a pair of tapered eyelets 18a on said hinged plate 18 willpass through the two apertures 24 of the base strip 21 which are inalinement with the apertures 16b in the base plate 17 and will extend ashort distance inside said sockets 16a. By means ot' this construct/on,the pad 10 will be detachably locked in any desired adjusted positionalong the length of the base strip 21.

In order to prevent the possibility of injury to the stocking or foot ofthe user, and also to :render the device more comfortable when worn in ashoe, the base strip 21 is covered with a protecting cloth 25 having'itsedges secured together as by a row of stitching 26, as clearly shown inFigs. 2 and 3.

In order to cushion the heel of the foot, a substantially semi-circularheel pad is mounted on the rear ofthe base strip 21. This heel padcomprises a top stiff leather plate 26a and a lower flexible leatherdisc 26" secured to the plate 26il in any suitable manner, as by asuitable adhesive. The rear end of the base strip 21 is adapted to befrictionally held between the top plate 26a and. the lower dise 26".

In operation, ythe callous protector will be placed within the shoe 2()under the foot 11 with the protecting pad 10 adjusted to the properposition justin the rear of the callous 12, as shown in Fig. 4. It willthus be seen that the weight of the foot will be kept Q ff, the callous12, permitting the blood to .riti

circulate therein and enabling the abnormal condition to be rapidlycured.

In the modified form of the .invention shown in Figs. 5 to T, a pad 27is provided which is similar in all respects to the pad l() previouslydescribed, The base strip in this instance` however, is made in twooverlapping sections 28 and 29 which are relativelyv slidable, so as toermit the callous protector to be readily a justed to fit various sizesof shoes. vThe front strip section 28 is provided at its rear end with apair of upwardly and inwardly directed flanges 30 and 31 which areadapted to form a guideway for the front part of the rear section Q9.The sections 28 and 29 are provided with spaced perforations 32 and 233which are adapted to be broughtI into alineinent with each other so asto permit the pair of holding screws 34 to be inserted therethrough forholding the sections Q8 and 25) and the protecting pad 2T in theirproper adjusted positions.

In order to provide a` cushion for the heel oft' the foot, a heel pad isprovided. This heel pad, as shown in Fig. 5 comprises a top stiif plate35 adapted to lie above the strip section 29 and a lower flexible plate36 adapted to lie under the section Q9. The plates 35 and 3G arepreferably substantially .semi-circular and constructed of leather. Theyare adapted`to be held securely to- ;cther by a row of stitches 87, asshown in Figs. 5 and 7.

While there have been disclosed in lthis specification two forms inwhich the invention may be embodied, it is to be understood that theseforms are shown for the purpose of illustration only, and that theinvention is not to be limited to the specilic disclosures but may bemodified and embodied in various other `forms without departing from itsspirit. In short, the invention includes all the inoditications andembodiments coming within the scope of the following claims.

Having thus fully described the invention, what claimed as new, and forwhich it is desired to secure Letters Patent, is:
